In this study, conversion as a function of dose was measured for a series of (meth)acrylates during electron beam (EB) and x-ray polymerization to characterize the impact of the irradiation mode. Monomer chemistry was shown to be a key variable in the comparison of the two technologies, providing guidance for application choices. Part 1, published in Issue 2, 2026, provided the … [Read more...] about Comparison of EB- and X-Ray-Initiated Polymerizations for Extending Radiation Curing Opportunities, Part 2

Advances in Photopolymer Design
The UV additive manufacturing techniques discussed in this column have focused primarily on hardware approaches to additive manufacturing or the chemistry developed in combination with those approaches. 1 The current column is a brief survey of chemistries developed to function within the existing printer hardware landscape to explore novel areas of material performance. These … [Read more...] about Advances in Photopolymer Design
Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 5
In four previous editions of UV+EB Technology, we discussed the preparation of nanocomposites made by incorporating carbon nanotubes (CNTs) into UV-polymerizable formulations. 1, 2, 3, 4 The first two of those articles summarized the experimental techniques developed by undergraduate students at the University of Houston-Downtown to determine how well single-walled carbon … [Read more...] about Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 5
Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 4
In three previous issues of UV+EB Technology, we discussed the preparation of nanocomposites made by incorporating carbon nanotubes (CNTs) into UV-polymerizable formulations. 1, 2, 3 The first two of those articles summarized the experimental techniques developed by undergraduate students at the University of Houston-Downtown to determine how well single-walled carbon nanotubes … [Read more...] about Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 4
